TI  - Postexercise protein-carbohydrate and carbohydrate supplements increase muscle 
      glycogen in men and women.

AB  - We have previously demonstrated that women did not increase intramuscular 
      glycogen in response to an increased percent of dietary carbohydrate (CHO) (from 
      60 to 75% of energy intake) (M. A. Tarnopolsky, S. A. Atkinson, S. M. Phillips, 
      and J. D. MacDougall. J. Appl. Physiol. 78: 1360-1368, 1995). CHO and CHO-protein 
      (Pro) supplementation postexercise can potentiate glycogen resynthesis compared 
      with placebo (K. M. Zawadzki, B. B. Yaspelkis, and J. L. Ivy. J. Appl. Physiol. 
      72: 1854-1859, 1992). We studied the effect of isoenergetic CHO and CHO-Pro-Fat 
      supplements on muscle glycogen resynthesis in the first 4 h after endurance 
      exercise (90 min at 65% peak O2 consumption) in trained endurance athletes (men, 
      n = 8; women, tested in midfollicular phase, n = 8). Each subject completed three 
      sequential trials separated by 3 wk; a supplement was provided immediately and 
      1-h postexercise: 1) CHO (0.75 g/kg) + Pro (0.1 g/kg) + Fat (0.02 g/kg), 2) CHO 
      (1 g/kg), and 3) placebo (Pl; artificial sweetener). Subjects were given 
      prepackaged, isoenergetic, isonitrogenous diets, individualized to their habitual 
      diet, for the day before and during the exercise trial. During exercise, women 
      oxidized more lipid than did men (P < 0.05). Both of the supplement trials 
      resulted in greater postexercise glucose and insulin compared with Pl (P < 0.01), 
      with no gender differences. Similarly, both of these trials resulted in increased 
      glycogen resynthesis (37.2 vs. 24. 6 mmol . kg dry muscle-1 . h-1, CHO vs. 
      CHO-Pro-Fat, respectively) compared with Pl (7.5 mmol . kg dry muscle-1 . h-1; P 
      < 0.001) with no gender differences. We conclude that postexercise CHO and 
      CHO-Pro-Fat nutritional supplements can increase glycogen resynthesis to a 
      greater extent than Pl for both men and women.
